I found this cool gadget today while surfing Marine Depot's blog. It allows you to add a background image, change the color of fish and the number of fish. You can also feed the fish by clicking on your left mouse button and the fish will swim over and eat the spot. Multiple clicks will add more food and make the fish go crazy after each spot. (Must be Reef Nutrition's Arctic Pods.) Please don't overfeed any display! You can add it as a screen saver on your computer if you'd like to customize it to your preferences HERE.
